The HATCHBOX 3D Printer User Guide : Lubrication, Screw Tension

Lubrication

To ensure the life of the rail, we recommend lubricating the linear rail every 200 hours or as needed.

Screw Tension

The 3D printer contains 12 core screws that will need to be fastened. Overtime, due to vibration and movement while printing, these screws may become loose. This will affect printing or may cause damage to the 3D printer. We recommend checking the screw tension daily.

Bed leveling for 3D Printer ULTIMAKER 2 EXTENDED+

Bed leveling

As explained in the Get Started section the first layer of a print is very important. Therefore regular bed leveling is advised. Always re-level the build plate when you notice that the plastic is not equally placed on the glass plate. After transportation of your Ultimaker 2 Extended+, it is also advised to re-level the build plate to ensure your 3D prints stick well to the build plate.

To start the bed leveling process on your Ultimaker 2 Extended+, go to "Maintenance" > "Buildplate". Wait for the Ultimaker 2 Extended+ to do its homing procedure and continue when the print head is in the center at the back of the build plate.

Setting the height

Roughly set the height of the build plate by rotating the button at the front until there is approximately 1 mm distance between the nozzle and the build plate. The measurement here is not critical; just make sure that the nozzle is close to the build plate without touching it.

Rough leveling

Adjust the front left and front right build plate screw to roughly level the build plate at the front side. Again, there should be a distance of approximately 1 mm between the nozzle and build plate. Turn the build plate screws to the left to move the build plate closer to the nozzle.

Fine-tuning

The last step will be fine-tuning of the build plate with the calibration card. Place the calibration card between the nozzle and build plate on all 3 points and adjust the build plate screws until you feel slight friction when moving the card.

Note: Don't push on the build plate while fine-tuning with the calibration card. This will lead to inaccuracies.

Buying a 3D Printer? - What You Need to Know

With the number of desktop 3D printers sold annually expected to see grow by a staggering 750% by 2019, and with the number of different machines on the market mushrooming over the last two years, it has come to our attention that an ever growing number of consumers are simply becoming overwhelmed. Way back in 2012 when I first purchased a 3D printer there were only a handful of reliable machines available on the market. Fast forward to 2015 and there are literally hundreds. Priced anywhere from $249 all the way up to thousands, I, myself, even feel a wee bit overwhelmed when friends ask me what they should buy.

If you are in the market for a new 3D printer, then there are a lot of decisions ahead of you. We’ve decided to put together a small guide which can be used in conjunction with our “Best 3D Printers of 2015” review article to hopefully help you select and buy the 3D printer which suits you and your activities best.

Buying a 3D Printer – A Starting Point…

When the typical consumer sets out to purchase a new 3D printer, they usually start with Google, or head directly to Amazon. Both are great starting points, but from a research perspective only. Use Amazon initially to read reviews on each product, noting that there are cheaters out there and not every review is legitimate. Next you should head over to the 3D Hubs 3D Printer review page, which takes into account, according to the company, 2,279 reviews, 335 writing hours, 1,623 years of experience, and over 317,000 individual prints to present a full picture of the consumer 3D printing space. Note that there is a ton of information on Amazon, Google, 3D Hubs. It’s impossible to take it all in, but very important that you spend time at least learning about the machines which consistently receive the better user reviews.

Price Doesn’t Mean Quality

Next it’s time to determine your budget. Money doesn’t grow on trees, but plastic objects do grow on all 3D printers. Don’t let the price tags fool you. There are many excellent machines available for under $1000, and a handful of great r3machines one can pick up for under $600. Don’t think that you need to spend $3,000 to really get involved with 3D printing. Price does not equate to quality all the time. I’ve used $500 printers which I thought worked better than $1,800 machines, while I’ve also used $500 machines which I would have been better off dropping off at the landfill than in my garage. Once again it all comes back to reading reviews and understanding what you need the printer for.

Money Spent Now = Money Saved Later

Contrary to what we just stated in the previous bullet point, oftentimes spending a little bit of extra money now could equate to savings in excess of that amount down the road. Let me explain…

I have 8 3D printers now. I like trying new machines and also received a few for review articles we’ve done. While price does not always mean quality, there have been a couple machines that I received which retail for around $500. One of these machines, in my opinion, was a total waste of time. I ended up spending $100 in filament alone because every time I left the the printer for a r2few hours to do its thing, I would return to find a 3D printed Salvador Dalí murder scene in my garage with melted filament strands strewn across the build plate like someone’s intestines had just ruptured. Frankly if you were to purchase this printer (I won’t mention the name right now) you’d likely be forced to buy a new one within months. Avoid such a mishap by reading reviews thoroughly!

Understand Your Abilities

This is one of the most important points. Those jumping into 3D printing for the first time, with little to no experience, often purchase the cheaper machines. While many of these machines work exceptionally well, a majority of them are very rudimentary. If there is a problem it might not be so easy to fix, and likely there are no features such as print bed auto-calibration, cloud-based printing, WiFi connectivity, etc., which make 3D printing a bit easier for the beginner. On the other hand if you have had experience with machines like these before, or are a mechanical genius, then it might r4benefit you to buy one of the more rudimentary, affordable 3D printers out there.

Know Your Ultimate Goals:

Like I’ve mentioned before, there are hundreds of 3D printers out there to choose from. Just like with any other major purchase, whether it’s a car, smartphone, or computer, not every item is right for you. You likely wouldn’t buy a sports car if you had a family of 7, just like you wouldn’t buy a minivan if it’s just you and your wife. 3D Printers are the same. Many of the machines and the technologies behind them are suited for specific uses. It’s important you understand the differences between each particular feature, technology, and specification. Spend some time learning about 3D printers in general before you even begin considering a purchase.

Buying a 3D printer can be an enjoyable, but oftentimes scary experience. If you come in prepared, invest the time necessary in researching the industry and understanding your needs, you’ll likely find a printer which provides years of useful fabrication.

PUSH MOWER BUYING GUIDE

How To Find The Perfect Push Mower For Your Needs

Buying a lawn mower may seem like a routine task. But to ensure that you buy the lawn mower that best meets your specific needs you’ll want to factor in the size of your yard, whether your yard is hilly or flat, the number of trees or other obstacles to mow around, as well as the needs of the person doing most of the mowing.

There are many different lawn mowers on the market to meet a variety of lawn mowing needs. A mower that is perfect for your neighbor may not be the right one for you.

To find a mower that meets your needs, follow the tips we’ve assembled for you in this helpful buyer’s guide

What Mower Is Right For You, Push or Self-Propelled?

Push Mowers are ideal for flat yards under ¼ acre. Their cutting deck ranges from 20-22 inches, which is the perfect size to quickly and efficiently make your lawn look beautiful. If you are in good physical condition this may be a great way to save when purchasing a new lawn mower.

Self-Propelled Mowers are perfect for yards up to ¾ acre. The mower actually pushes itself to reduce fatigue that may come with a push mower. You simply walk behind the mower to control its path. Self-Propelled lawn mowers offer both front and rear wheel drive to better suit your yard. See below to determine which is right for you:

Front-drive push mowers are remarkably easy to maneuver and turn. Swivel front wheels make this possible by allowing easy 180-degree turns. These are perfect for smaller yards with numerous obstacles.

Rear-wheel drive mowers have better traction on hills and better steering control, but may make it a little harder to make sharp turns. These mowers are suited for open yards with steep hills.

If your lawn is larger than ¾ acres you may want to consider a Riding Lawn Mower.

Lawn Mower Features: Choosing The Features Right For You

Starting Systems - An easy-starting lawn mower is one of the most important features to get the job started right. That’s why selecting the right starting system is vital in ensuring you a hassle-free lawn mowing experience.

Electric Starting Systems eliminate pull starts all together. Simply prime the engine and turn the key for quick, dependable starts without any maintenance required.

Automatic Choke Starting Systems come ready to run. Simply engage the safety handle and pull the starter rope for a hassle free start that completely eliminates priming or choking.

Primer Starting System pumps the exact amount of gas into the carburetor to allow quick and easy one pull starts.

No Prime. No Choke. No Problem The ReadyStart™ system from Briggs & Stratton helps eliminate the strain and the hassle of starting your lawn mower. Manual priming and choking are now a thing of the past. Simply pull the rope and mow. The ReadyStart™ system makes starting Briggs & Stratton power products easier and faster.

What To Do With The Clippings

Bagging is a technique used to catch cut grass. They are available as both rear and side bagging mowers. Rear bagging mowers give you more maneuverability around trees and landscaping throughout your yard. Bagging leaves you with a fresh looking lawn every time you mow.

Mulching mowers use mulching blades that cut the grass into fine piece and return them to your lawn to act as a natural fertilizer. This works to enhance your lawn and does not require any extra time or money. It also eliminates the time you may spend emptying the grass out of a bagging mower.

Additional Features

Leaf-Handling Capability. These mowers suck up, shred and catch leaves with a screen that goes between the cutting blade and the discharge chute. Several newer mowers offer this unique feature.

Sound Quality: Briggs & Stratton offers specially designed mufflers to reduce to the sound of your mower during operation.

Durability: When purchasing a lawn mower, look for engine features like Maxi-Clean™ filters and overhead value technology (OHV) that help make your lawn mower engine last a lifetime.

Safety Tips: Be Careful Out There

According to the US Consumer Product Safety Commission, more than 60,000 injuries are treated by hospital emergency rooms each year because of unsafe operation of power lawn mowers. Kids under the age of 15 are the most common victims. Regardless of which mower you choose, don’t forget to practice safety. We’ve assembled some guidelines below to help keep you safe while using your equipment:

Always wear protective eyewear.

Mow only in daylight, when the grass is dry.

Check your yard for any debris or objects, such as toys that could pose a hazard if you mowed over them.

Keep you children and pets out of the mowing area.

Never let the starter rope snap back when starting a mower.

Look three to four feet directly ahead of you while mowing.

Never tilt a mower; always keep all four wheels on ground.

Take special care when mowing hills and inclines:

With your push mower, always mow across an incline or hill

Always turn off mower when crossing a sidewalk or driveway.

Never adjust mower height, clean grass chute, remove grass catcher or repair the mower while the engine’s running.

Never de-activate safety devices.

Never pull mower towards you.

Always stay clear of a hot engine. Mufflers can reach up to 1,200˚F.

Always read your Operator’s Manual thoroughly before operating the mower.

Children under 12 should not operate a push mower.

Maintenance Tips: For Long Life and Safety

Lawn mowers are built to last. However, as with any power product basic maintenance can be the difference in ensuring that your investment lasts a lifetime. Below is a basic maintenance schedule that should be followed by every lawn mower owner:

Check Oil Level - Every 5 hours

Change Oil - 50 Hours or every season

Replace Oil-Foam Element- 25 Hours or Every season

Replace air-cleaner cartridge - 25 Hours or Every season

Clean cooling system - 100 Hours or Every Season

Inspect spark-arrester - 50 Hours or Every Season

Replace in-line fuel filter - 50 Hours or Every Season

Replace spark plug - 100 Hours or Every Season

Clean combustion chamber deposits - Every 100-300 Hours

A Bluetooth smartphone allows individuals to connect to any device featuring Bluetooth technology. Wi-Fi smartphones allow the user to switch off mobile data, such as 3G or 4G networks, and to use in-house Internet-connectivity. This can reduce costs.

Other Connection Options

Some smartphones connect through USB ports. For a user who travels internationally, a Global System for Mobile Communications smartphone, also known as a GSM smartphone, is ideal. It is important for users to consider usability with their preferred carrier, too.

Determine Which Features are Ideal

Based on the way the buyer plans to use his or her smartphone, it is essential to consider features. Some people have preferences to one style of phone or another. Technology continues to update and new features continue to become available.

Keyboards

A QWERTY keyboard pulls out from the phone and allows the user to type on keys, much like a traditional computer keyboard. Many people purchase touchscreen smartphones. These have built-in keyboards that operate based on an on-screen keyboard.

Cameras

Smartphones with cameras are very common. The quality of the camera tends to differ from one model to the next. When comparing options, buyers need to factor in the number of megapixels, the zoom quality, and the overall quality of images. Many also feature video cameras and media players to allow for on-screen viewing.

How to Buy a Smartphone

The selection of a smartphone requires the buyer to consider his or her desired features and specs. With numerous options available on eBay, buyers have the ability to easily compare various makes and models online and within a matter of seconds. To do so, buyers can visit any page of the eBay website and use the search bar on the screen to locate a specific brand, style, or operating system available. Then, the consumer can navigate through various vendors to locate a new or used cell phone, a locked or unlocked phone, or one with specific features. By comparing numerous options, it is possible to narrow down the buying decision until the ideal investment is possible.

Yuneec Typhoon Q500 4K review

Camera options for your average consumer drone are limited to either a mount for a GoPro or similar camera or a built-in camera that is permanently attached to the drone. The former is fine, though it may or may not give you a first-person view (FPV) from the air and it's one more thing to keep charged (and you'll have to figure in the extra cost of the camera). The latter, however, means you've got no upgrade path should a better camera come along, and it can only be used with the drone.

Yuneec's Typhoon Q500 4K is not your average drone. Slung from the belly of the $1,300 quadcopter (£960 AU$2,200) is a 4K-resolution camera combined with a three-axis antivibration gimbal. When not in the air, the camera-and-gimbal system can be quickly removed and attached to the included SteadyGrip, a battery-powered handheld mount that lets you use the Typhoon's camera on the ground. Combined with an iPhone or Android smartphone, you can shoot completely control the camera and see what you're shooting. (Yuneec makes an updated and improved version of the SteadyGrip called ActionCam with a built-in rechargeable battery and the Q500 4K's CGO3 camera.)

The DJI Inspire 1 series takes a similar approach, but it's targeted at professionals and starts at about $2,700 for the drone and the handheld camera mount is an additional $270. The Typhoon Q500 4K is a better option for beginners, giving you an aerial and ground imaging solution that, while maybe not as feature-filled as some competing models, does what it does very well.

Design and features

The Q500 4K is big. Not like "How does that thing get off the ground?" big, but next to the relatively compact DJI Phantom 3, it's big. (The diagonal motor-to-motor measurement is 390mm for the Phantom compared to the Typhoon's 510mm.) The size does make it easier to spot in the sky from a distance, but you're not sliding the Q500 4K easily into a backpack for a trip to the park.

Instead Yuneec packs everything into a large, sturdy case. Along with the drone and its camera you'll find two batteries and a charger; two sets of propellers; the ST10+ controller, a neck strap and sunshield; a cable to use the charger in a car; and the SteadyGrip handheld mount. Unfortunately, Yuneec used Styrofoam inside the case instead of something a bit more long-lasting.

The Styrofoam is representative of the design and build quality on the whole: it's a good package overall, but lacks some polish. The black-and-gray plastic body looks nice, but pick it up and it feels a little flimsy. It's great that the camera can be removed, but to do it you have to keep plugging and unplugging this small cable and pushing in a plastic tab, both of which I feel might not last with frequent use. Nothing that's a deal breaker, but a little disappointing.

The controller for me is definitely a plus, though. Instead of relying on a tablet or smartphone for a live view from the camera as well as flight information, the ST10+ has a built-in 5.5-inch touchscreen display built right in. There's a bit of lag between the camera and screen, so I wouldn't recommend flying by FPV alone, but for setting up shots and giving you telemetry data at a glance it's great. It also means you only have to worry about having the controller charged, not a second device.

Having the fixed screen does mean you can't go with a larger tablet display, but since the drone doesn't support waypoint navigation -- where a larger screen to set up an autonomous flight path comes in handy -- and FPV flying isn't a great idea, it's not a big loss.

The controller also has buttons for starting and stopping video recording and snapping photos and sliders for setting the camera angle and limiting overall climb/descend and directional speed. A switch lets you move between flight modes: Smart, Angle and Home.

Smart mode is made for beginners. In addition to enabling a virtual barrier called a geofence to prevent it from flying more than 300 feet away from the pilot, the controller will always move the Q500 4K in the direction the right-hand control stick is pushed relative to the pilot and no matter which way the nose is pointed. It's fine if you've never flown before and you use it just to get a feel for how the quadcopter will fly, but I don't recommend using it much beyond that.

However, Smart mode is the only way you can use two of the drone's main attractions: Follow Me and Watch Me modes. With Follow Me, the drone uses a GPS signal from controller to follow whoever or whatever is carrying it. Watch Me mode works similarly, but keeps the controller -- or whoever's holding it -- framed in the camera no matter where and how it moves and the camera can automatically tilt according to the controller.

Carrying around a big controller doesn't make for the best video, though, so Yuneec developed the Wizard remote control. It's about the size of a TV remote, but can completely control the drone with simple gestures and a directional pad. It also has GPS in it, so it can be used with the Q500 4K's Follow Me and Watch Me functions.

If you want to actually pilot the Q500 4K normally, just switch into Angle mode. This will move the drone in the direction the control stick is pushed relative to the nose of the aircraft. As long as you've got a lock on six or more GPS satellites, the Q500 4K will automatically hold its position and hover in place when the right-hand stick is centered.

The Home mode is the drone's return-to-home safety feature. Flip the switch down and as long as the drone has a solid GPS lock and there are no obstacles in the way, it will fly back to within 13 to 26 feet (4-8 meters) of the pilot and automatically land.

Flight

Setting up the Typhoon Q500 4K for flight is about as simple as it gets. Spin on the props, charge up the batteries for the drone and controller and you're done. The controller, which is running on Android, takes a minute to boot up and then, once you've turned the drone on, it takes another minute for the two to finish connecting. GPS satellite acquisition -- required for hovering in place and return-to-home among other things -- takes a little more time. All told, it took me about 3 to 5 minutes until it was ready to fly, basically depending on how fast I could lock onto more than six satellites.

There is no automatic takeoff, but the procedure is simple enough: Press and hold a button on the controller to set the motors spinning and press up on the left stick. There is also no automatic landing, though you can just switch to Home mode and it will land for you. Honestly, other than bouncing a bit when it's close to the ground, the Q500 4K is stable enough for beginners to take off and land without issue.

As long as it's locked onto plenty of satellites, flying is easy. It's not particularly zippy, but that's kind of a plus when you're learning to fly for smooth camera movements. It is remarkably quiet, too. Yes, you'll still hear it, but it's more like the sound of a fast-spinning fan than an electric leaf blower.

I occasionally experienced some erratic flight behavior, but calibrating the drone's compass seemed to straighten it out. The procedure isn't difficult, though the drone's size makes it awkward since it involves turning and rotating the copter several times. Also a recent firmware update improved performance all around. (That procedure requires little more than connecting the Q500 4K to a computer via USB.)

All in all, flying the Typhoon is a pleasurable experience. Flight times for me averaged around 20 minutes before the controller started warning me to land, which is typical battery life at the moment for this category. Perhaps because of its larger size, it moved smoothly and while there is some lag between the camera and the what's displayed screen, the controls were responsive.

Video quality

Yuneec gives you several resolutions to choose from for video, the highest being 4K Ultra HD (3,840x2,160 pixels) at 30 frames per second, but also does high-speed video in full HD (1,920x1,080 pixel) at 120fps for slow-motion. It records at a high bitrate of 50Mbps, and it shows in the details. Subjects look sharp (maybe a little too sharp), though on my camera subjects on the far left side appear softer.

The three-axis gimbal does a fine job of keeping the camera stable, so even if you're not making steady moves with the drone it won't show in your clips. You'll still see some of the effects of rolling shutter, but that's typical for the category. The video is best viewed at small sizes in general, so if your goal is to share your videos online and watch them on a phone or tablet, the Q500 4K's camera will yield some excellent clips.

Conclusion

Thanks to some useful accessories and a solid feature set, the smooth-flying, easy-to-use Yuneec Typhoon Q500 4K quadcopter is a compelling package for video and photos in the sky or on the ground. The design is a little rough around the edges, and if you want autonomous flight features like waypoint navigation, you're out of luck. Otherwise, this is one nice drone for the money.
